Due to the advancement of industrialization and the development of the metal smelting
industry, cadmium (Cd), as a highly toxic heavy metal element, is discharged into the natural …

Column leaching experiments are an essential step in the upscaling process towards a
heap leaching operation. However, these experiments are often restricted to the optimisation …

Chalcopyrite (CuFeS 2) is the primary ore mineral for copper, but leaching of this mineral
under atmospheric conditions is slow due to the formation of surface passivating phases …

Pore defect elimination is the most effective way to prolong the service life of Fe-based
amorphous coating. In this study, the passive sealant (PSG) was successfully prepared by …

Pyrite is the most abundant metal sulfide in the Earth's crust and is also found on Mars. It can
form by direct hydrothermal precipitation or by polymorphic phase transformation from …

In the process of extraction of gold from refractory sulphide ores, arsenopyrite and pyrite
represent two of the major hosts for gold in solid solution. In this study, the pressure …

Organic solutions are promising lixiviants for fast and environmentally sustainable Pb
extraction from ore minerals at low temperatures. However, engineering of novel leaching …

Dissolved iron exerts significant effects on mineral leaching, impurity removal, and solution
purification in the zinc hydrometallurgy process. To date, iron oxidation and migration …

The main problem associated with the oxidative leaching process of sphalerite is the slow
dissolution rate in acidic ferric solution due to the formation of a passive layer on the …

Zinc is currently extracted from sphalerite (ZnS) by either sintering-smelting or roasting-
leaching. These high-temperature processes produce environmentally hazardous sulfur …
